Abstract

Mg-Mn-Ni ferrites of different compositions, Mg0.40 Mn0.60-x Nix Fe2 O4 with x = 0.00, 0.05 and 0.15 were prepared by a co-precipitation technique at 30°C to 60°C. Their structural and dielectrical properties were studied using XRD, SEM and AFM analyses, FT-IR technique and impedance analyses. From these, we observed that Mg-Mn-Ni ferrites prepared by this method have higher resistivity than that prepared by the conventional ceramic method and others. Higher resistivity ferrite materials are suitable particularly for high-frequency applications where eddy current losses are required to be low.
